Section 98 — "Transfer" and "revocable transfer" defined
In plain terms: This section defines "transfer" (it includes any settlement, trust, covenant, agreement or arrangement) and when a transfer is "revocable" (for example if it lets the transferor take back the assets or income or regain power over them) for sections 96 and 97.
For the purposes of sections 96 and 97, and this section,--
(a) "transfer" includes any settlement, trust, covenant, agreement or arrangement;
